I + 61 303 as a potential neutrino source on the light of MAGIC results

High energy γ-rays have recently been detected from the microquasar LS I +61 303 using the MAGIC telescope. A phenomenological study on the concomitant neutrinos that would be radiated if the γ-ray emission is hadronic in origin is herein presented. Neutrino oscillations are considered, and the lower limit to the expected number of events in a km-scale detector such as ICECUBE is computed under different assumptions including orbital periodicity and modulation. We argue that the upper limits already imposed using AMANDA-II and the forthcoming measurements by ICECUBE may significantly constrain -in an independent and unbiased waythe γ-ray to neutrino flux ratio, and thus the possibility of a hadronic origin of the γ-rays. The viability of hadronic models based on wind-jet interactions in the LS + 61 303 system after MAGIC measurements is discussed.
